Is there a function that will remove any symbols (%, #, & ect.) from a string?

Question

I want to remove ALL symbols from my string efficiently.

x = hello!!
r = dict.fromkeys(map(ord, '\n ' + string.punctuation))
x.translate(r)

I expected this to remove all symbols instead of only a full stop (.)

What dou mean by symbols? Do you want to keep only ascii-chars? Only letters and numbers? — k0pernikus, Sep 10 '19 at 09:51
Yeah, I would like to keep letters and numbers and remove all other characters such as punctuation — CAKEe, Sep 10 '19 at 09:55

What about using re.sub to remove all string.punctuation and ' \n':

x = re.sub('|'.join(map(re.escape, string.punctuation + ' \n')), '', x)

You could also use the following regex if you want to keep only alphabet and digit characters:

x = re.sub('[^a-zA-Z0-9]', '', x)
